My advice to any clients using the reviews system:
- Read the reviews. Don't just look at the green and red crosses and the rats in the reviews list, but really read individual reviews. There is no substitute for that.
- You won't be able to identify all the fake reviews. Don't even try. Look for genuine reviews instead. There is a small minority of reviewers I trust. Of the others, some are fake and some are genuine, but I don't expect to be able to sort out which are which.
